This form of scarf and resilient connection forms a serviceable track structure for employment upon any form of railroad with or without ties such as wood, metal or concrete ties. While the form of the invention herein set forth is believed preferable, it will be understood that changes may be made therein without departing from the spirit and scope of my invention.

WVhat is claimed as new is:

A device for applying resilient bolt members to rail ioints having overlapping web portions comprising a body adapted for receiving the head of the bolt for turning, an operating lever for said body, a compression lever journaled upon said body and projecting above the tread of the track when in use, and a hook swingingly carried by said compression lever adapted for engagement over the tread of the rail above the plane of the bolt being operated upon whereby the bolt may be shifted longitudinally and revolved during the operation of the device.

In testimony whereof I affix my signature.

JOHN NELSON.
